DNA Replication

Front

What is DNA Replication?

Back

The process by which a cell makes an exact copy of its DNA, resulting in two identical DNA molecules.

Front

What is the role of DNA Polymerase in DNA replication?

Back

DNA Polymerase is the enzyme responsible for adding nucleotides to the growing DNA strand during replication.

Front

What does DNA replication result in?

Back

2 DNA molecules that each contain one strand of the original DNA.

Front

What is the function of Primase in DNA replication?

Back

Primase synthesizes short RNA primers that provide a starting point for DNA synthesis.

Front

What is the role of Helicase in DNA replication?

Back

Helicase unwinds the double-stranded DNA, separating the two strands to allow replication to occur.

Front

What are the base pairing rules in DNA?

Back

Adenine pairs with Thymine (A-T) and Cytosine pairs with Guanine (C-G).

Front

What is the significance of the leading and lagging strands in DNA replication?

Back

The leading strand is synthesized continuously, while the lagging strand is synthesized in short segments called Okazaki fragments.

Front

What is an Okazaki fragment?

Back

Short segments of DNA synthesized on the lagging strand during DNA replication.

Front

What is the function of Ligase in DNA replication?

Back

Ligase joins Okazaki fragments together on the lagging strand, sealing the gaps between them.

Front

What is the difference between replication and transcription?

Back

Replication copies the entire DNA molecule, while transcription synthesizes RNA from a DNA template.
